Look, it's possible: it doesn't always have to be a superbike costing 30,000 euros or more to have fun in the saddle - whether on the race track or in everyday use. Of course, the QJ Motor SRK 600 RS is not a superbike, but a sporty entry-level and mid-range bike for price-conscious buyers who don't want to compromise on features and looks. If QJ now puts the finishing touches to the ABS and traction control setup, then this will be a respectable debut for the Chinese manufacturer in the highly competitive European premium two-wheeler market.

extensive features for this segment

soft engine tuning

everyday-oriented suspension tuning, very good for country roads

surprisingly grippy CST tyres fitted

high-quality components installed (Brembo, Marzocchi)

large 5-inch TFT display with connectivity

ABS control interval too long (software update should bring improvement)

Traction control regulates harshly

For taller riders with large feet (from shoe size 44) cramped space when changing gear

No quickshifter
